This selection manager synchronizes a local set of selected features with an attribute table.
Is an interface class to abstract feature selection handling.
virtual void select(const QgsFeatureIds &ids)=0

virtual int selectedFeatureCount()=0
Returns the number of features that are selected in this layer.
virtual const QgsFeatureIds & selectedFeatureIds() const =0
Returns reference to identifiers of selected features.
virtual void deselect(const QgsFeatureIds &ids)=0
Deselect features by feature ids.
virtual void setSelectedFeatures(const QgsFeatureIds &ids)=0
Change selection to the new set of features.
